Abstract
The factors affecting the rate and extent of the spillover of hydrogen and the reverse phenomenon in a variety of catalysts containing WO3 and MoO3 have been studied by volumetric measurements, cyclohexene dehydrogenation and pent-1-ene hydrogenation. Primary spillover in systems where initiating and accepting phases are in contact is faster and more extensive than secondary spillover in systems where these phases are not in contact. Only the latter type of spillover may be increased by the presence of H2O but its reversal is not so accelerated.Keywords
